C/2015 V2 Johnson
Closest to Earth on 2017 June 5 at 0.81AU.
Closest to Sun on 2017 June 12 at 1.63AU.
Maximum magnitude 7.5 in June 2017.
Orbital period: N/A (parabolic.)
Was yet another disappointing dynamically new comet entering the solar system, failing
to reach its expected peak of magnitude 5-6,
only managing to reach magnitude 7.5 at best when well situated for viewing in evening skies during June, trekking southwards.
At the beginning of March 2017, comet Johnson was located in Hercules,
low in the northeast before dawn.
The comet trekked very slowly eastwards during the month.
By the end of March, the comet had brightened to magnitude 9.5
At the start of April 2017, the comet remained low in the northern morning sky, near the vicinity of Tau Herculii.
Moonlight interfered from April 9.
At the start of May 2017, the comet was located low in the northern morning sky, near the vicinity of Phi Herculii, shining at magnitude 8.5
Moonlight interfered from May 6.
By May 16, the comet rose at 8pm local time, prior to moonrise.
It continued its trek southwards at 1 degree per day, becoming more visible for southerners.
Comet Johnson appeared moderately condensed, with a bright dust tail through telescopes.
By the end of May, the comet was situated 8 degrees Northeast of Arcturus in
Bootes and had brightened to magnitude 7.5
Comet Johnson was well situated for viewing in southern hemisphere evening skies after June as it trekked southwards overhead.
At the start of June 2017, the magnitude 7.5 comet was located low in the north-eastern evening sky, near Arcturus in Bootes.
However moonlight interfered until the evening of June 12. On this date, the comet was situated to the south of Arcturus.
A photographic opportunity occurred on June 18 when the comet rendezvoused with galaxies NGC 5566,5576 in Virgo.

Moonlight started to interfere by months end and on July 1, the comet
found near Kappa Virginis.
During July, comet Johnson continued its southerly trek during evening hours but started to fade.
The first opportunity for dark sky viewing occurred on the evening of July 11 when the comet appeared magnitude 8.

At the start of August, the magnitude 8.5 comet was located in Centaurus, about 6 degrees NE of Theta Cen, although moonlight interfered.
Between August 23rd-25th, the comet will be situated less than 1 degree from Kappa Cen and magnitude 12 spiral galaxy NGC 5786.
On the 26th, the now magnitude 9.3 comet moved into Lupus, and moonlight once again interfered
During September, comet Johnson continued its southerly trek through Lupus, Norma and Ara, during evening hours.
At the start of September, the magnitude 9.5 comet was located in Lupus, between Epsilon and Lambda Lup, although moonlight interfered.
It was 15' NE of planetary nebula NGC 5882 on Sep 3.
On September 14, the now magnitude 10 comet crossed into Norma
